Item No. 747-10010
Manuf. No. Howie Glatter HGLC2-650B

A single beam laser can be used to align the secondary mirror to the focuser axis. When the primary is aligned, however, a Barlow must be used to align the return beam-the single beam is not accurate enough. Howie Glatter can provide a Barlow attachment with the laser (order a laser with the self-Barlow attachment), you can use your own Barlow, or you can buy a Howie Glatter BLUG to fit your focuser (simply the easiest way to use a laser for primary collimation).
